Remarks

General Remarks: Redescription in Suh and Evans, 2016.

Biology: Species in the genus are found on conifers only.

Systematics: This genus is closely related to Diaspis Costa, but differs mainly by possessing gland spines
between the median lobes and submarginal dorsal macroducts absent from abdominal segment 6 (Gill
1997). Species belonging to Carulaspis occur on conifers only, and are regarded as Palaearctic in origin (Williams and Watson 1988; Miller and Davidson 2005).

Structure: The adult females are almost circular to turbinate in shape, with the pygidium slightly pointed at apex, with median lobes small, rounded, separated by a space, L2 bilobate with medial lobule almost as large as L1, lateral lobule very small, L3 very small. With short gland spines between lobes and on abdominal margins. Marginal macroducts barrel-shaped, 4-6 pairs present, with or without a macroduct in medial space. Dorsal ducts arranged in short submedial and submarginal rows, with a few similar ducts on ventral submargin of abdomen. Anal opening a little posterior of mid pygidium. Microducts present on submedian dorsum and venter. Antenna with 1 seta. Anterior spiracles each usually with a trilocular pore, posterior spiracles without pores. Perivulvar pores in 5 well separated, rounded groups. (Henderson, 2011)
